Definitions

• the present application relates to novel substituted fused cyanopyridine derivatives, to processes for their preparation, to their use for the treatment and/or prevention of diseases and to their use for preparing medicaments for the treatment and/or prevention of diseases, preferably for the treatment and/or prevention of cardiovascular disorders.
• Adenosine a purine nucleoside
• Adenosine is present in all cells and is released by a large number of physiological and pathophysiological stimuli.
• Adenosine is formed intracellularly as an intermediate during the degradation of adenosine 5′-monophosphate (AMP) and S-adenosylhomocysteine, but it can be released from the cell, in which case it acts as a hormone-like substance or neurotransmitter by binding to specific receptors.
• AMP adenosine 5′-monophosphate
• S-adenosylhomocysteine S-adenosylhomocysteine
• adenosine inhibits platelet aggregation and increases the blood supply to the coronary arteries. Furthermore, it acts on the blood pressure, on the heart rate, on the release of neurotransmitters and on lymphocyte differentiation. In adipocytes, adenosine is capable of inhibiting lipolysis, thus lowering the concentration of free fatty acids and triglycerides in the blood.
• the aim of these actions of adenosine is to increase the oxygen supply of the affected organs and/or to reduce the metabolism of these organs in order to adjust the metabolism of the organ to the blood supply of the organ under ischemic or hypoxic conditions.
• adenosine-receptor-selective ligands are substances which bind selectively to one or more subtypes of the adenosine receptors, thus either mimicking the action of adenosine (adenosine agonists) or blocking its action (adenosine antagonists).
• adenosine receptors are mediated intracellularly by the messenger cAMP.
• the intracellular cAMP is increased via activation of the membrane-bound adenylate cyclase, whereas binding of adenosine to the A1 or A3 receptors results in a decrease of the intracellular cAMP concentration via inhibition of adenylate cyclase.
• adenosine receptors In the cardiovascular system, the main consequences of the activation of adenosine receptors are: bradycardia, negative inotropism and protection of the heart against ischemia (“preconditioning”) via A1 receptors, dilation of the blood vessels via A2a and A2b receptors and inhibition of the fibroblasts and smooth-muscle-cell proliferation via A2b receptors.
• A1 agonists (coupling preferably via G i proteins)
• a decrease of the intracellular cAMP concentration is observed (preferably after direct prestimulation of adenylate cyclase by forskolin).
• A2a and A2b agonists (coupling preferably via G s proteins) lead to an increase and A2a and A2b antagonists to a decrease of the cAMP concentration in the cells.
• a direct prestimulation of adenylate cyclase by forskolin is of no benefit.
• A1 receptors In humans, activation of A1 receptors by specific A1 agonists leads to a frequency-dependent lowering of the heart rate, without any effect on blood pressure. Selective A1 agonists may thus be suitable inter alia for treating angina pectoris and atrial fibrillation.
• the cardioprotective action of the A1 receptors in the heart may be utilized inter alia by activating these A1 receptors with specific A1 agonists for treatment and organ protection in cases of acute myocardial infarction, acute coronary syndrome, heart failure, bypass operations, heart catheter examinations and organ transplantations.
• the activation of A2b receptors by adenosine or specific A2b agonists leads, via dilation of blood vessels, to lowering of the blood pressure.
• the lowering of the blood pressure is accompanied by a reflectory increase in heart rate.
• the increased heart rate can be reduced by activation of A1 receptors using specific A1 agonists.
• Dual A1/A2b agonists having such a pharmacological profile could be employed, for example, for treating hypertension in humans.
• selective A1 antagonists can be suitable inter alia for treating acute heart failure and chronic heart failure. Furthermore, they can be used for renoprotection in cases of nephropathy and other renal disorders.
• A1/A2b agonists In adipocytes, the activation of A1 and A2b receptors leads to an inhibition of lipolysis. Thus, the combined action of A1/A2b agonists on lipid metabolism results in a lowering of free fatty acids and triglycerides. In turn, in patients suffering from metabolic syndrome and in diabetics, reducing lipids leads to lower insulin resistance and improved symptoms.
• the abovementioned receptor selectivity can be determined by the effect of the substances on cell lines which, after stable transfection with the corresponding cDNA, express the receptor subtypes in question [see the publication M. E. Olah, H. Ren, J. Ostrowski, K. A. Jacobson, G. L. Stiles, “Cloning, expression, and characterization of the unique bovine A1 adenosine receptor.
